Abstract
Supercurrent fluctuation of a mesosocopic Josephson junction (MJJ) in the pre-sense of a dc static voltage and a time-varying quantized elec tromagnetic field (QEMF) is investigated. It is shown that the fluctua tion of supercurrent in the MJJ exhibits periodical oscillations with a periodicity which depends upon the rate of the classical static exte rnal voltage and the frequency of the QEMF.
